LCi-rAnnnsaTnoivnis Con, citizen ofthe United States, and a resident of Albany, in the county of Albany; and State of NewuYork, have invented oertain newand useful Improvements .111 Sec tional Shaking and Dumping Grates of which the following is a specification. This invention relates to a sectional shake ing and dumping grate, which is character ized bv dumping'frames withgrate sections,

and meanst'o secure the latter insaid frames and prevent their detachment when using the grate. .71 l: 1 r t Figure 1 represents a plan view of agrate the invention, Fig.2isa partialfront view and section of Fig; 1. ontheline 2, 2, Fig. 3 shows a partial front view of Fig.1, Fig.4 is an enlarged fragmentary portion of Fig.

Fig. 10 is a section of Fig. 7 on the linen 10, 10, F igs. 11 and 12 show sections snnllar to Fig. 10'with modifications, Fig." 13 shows a .front view of a grate section, Fig. 14: showsa side view of Fig. 18, F ig. 15represents a top plan view of Fig. '14-, Fig. 16 shows a front elevation of a filling block, Fig. 17 is a right hand side view of-Fig. 16, and Fig. 18. represents a top plan view :of Fig.16. 1 m

The invention comprises a furnace having the supporting side bars 20 with .the sockets 21 having cylindrical bearings 25 of greater diameter, than the distancebetween the vertical walls of the'sockets, and the sockets 26 ;.;with cylindrical bearings 27 of a diameter equal to the distance between the walls of.

the sockets. In the ends of the said bars are formed dovetailed sockets 22, that engage lugs 28 of cross braces 24, which latter conneet the ends of said frames. 7

Between the supporting bars 20 are located the dumping frames 80 comprising the end walls 31 and intermediate walls 32 and 33. The end walls'31 have each exj'tending therefrom the segmentaltrunnions 34 with the flat faces 35, and the saidtrunnions are supported in the sockets of the snor'roiiensnanine AND DIEMP ING GRATE.

i said frames 20. ,Witliintermediate wall 32 isformed a leg 36hav1ng the pin 37. The dumplng'frames have the connecting Grate sections 5.0 are located between the it walls 32, 33' and bear'on the bearing brac'es.42,43. Each grate section comprises v theYbars 51 that are formed with the con- 'necting braces 52. :The grate bars 51' are I curved at their upper edges Land at their front ends have formed therewith the'heels 53that bear on the braces 1 13, and [at their front 'ends have the inclined bearing =sur- I faces 54, that bear on the bracesi2 which 3 latterare beveled to gage .with'the said inclin'ed. bearing surfaces. From-each grate, section extendsa lug 60, that is formed with a pair of the grate barsof said section Fromeach lug extends a hook clamp 61 that engages with one of the lugs 41of the,

connecting brace'lO. It will benoted that-j the lug 60- eXtends below one of the connecting braces 52 so as not to obstruct the open L ing between them, although-it nay be located between them.

The pins 87 of the legs 3.6 of a number of the dumping frames 30 are joined bythe connecting bar having the upper member 65' and the lower member 66. I From thelatter bearon the flat faces 35 of the segmental "trunnions 34, the ribs .81 being located between th end faces of the trunnions of accompanying dumping frames 30. In aside frame that would be adjacent to a brick wall of a furnace oneof the sides of the parallelepiped of the block would be adjacent to said wall.

In'Fig. 8 a fragmentary portion of a dumping frame is shown with a forked leg 83 and pin 84, in place of the leg'36 with the pin 37. I

In F ig. 11 a dumping frame is shown which has end walls, intermediatewalls and I connectinglbracessimilar to that shown in r the dumpi'ngframe 30. It has a bearing brace 91 similar to 42, and its accompanying bearing brace92 has formed therewith a shoulder 93 to support the heels 94 of the grate sections 9.5. The latter hasextending from its grate bars a lug 96 which is in a plane about midway between the connecting braces 97 of the grate bars of the section.

A hook clamp98 similar to 61 extends from the lug .96 and engages thelug 99 of the connectingbrace. 1 I 'Iill lg. 12 a dumping frame is shown similarito that represented in Fig. 10, the

modification consisting inthe hook clamp 100, which in this-case is bent under the connectingbrace 101 instead of engaging a lug of the latter;

- To use the grate the operator preferably by means of ashaking'bar, reciprocatesone ofxthe shaking links 77 andthereby one of the sets "ofdumping frames is moved thereby. .lVhenthe frames 30 are swinging from theirnormal positions the flat faces of the trunnions 3l-raise the filling blocks .in the sockets above the upper faces of the bars 20disin'tegrating any portions of fuel thereon that may be coked, thereby'preventing any fuel or ashes clogging up said sockets and packing 01*Cflklng1tl0lllld the trunnions so as to prevent their oscillations. The ribs 81' of the, filling blocks maintain them'in proper position when they are rising or lowering. a

The segmental trunnions of the dumpingcated in place. This disposition of the parts locks the dumping frames with the main side frames and allows the former to swing, and prevents the dumping frames being lifted from the main frames when the" grate is either dumped or shaken. This obviates 2 i p I 1,121,001

the usual unmechanical and complicated means of looking a dumping grate to a bar with wedges or blocks, and obtains an easy means to disengage the dumping frames from the side bars.

i The endsockets as 26 must have a distance between their vertical walls equal to the diameter of the bearings, so'that the end dumping frames can be lifted from and inserted in the main side bars without tilting. Some of the othersockets are preferably of I the same proportions so as to prevent the necessity of removmg too many dumplng.

frames when one of them is to be replaced. The dumping frames can be combined as desiredf All may be operated at once, or various members may be connected with one reach rod.

- Having described my invention, I claim: 1. In a grate the combination of supporting bars having sockets, each with a pair of parallel walls extending from the upper edge of each bar, the said walls connected by curved. bearings of greater diameter than the distancebetween said walls, dumping frames for the grate having segmental trunnions extending from the sides thereof, the

said trunnions supported on said curved bearings and locked from displacement by said parallel Walls, and means coacting with saidtrunnions and sockets when moving the dumping frames to disintegrate any portions of fuel thereon.

2. In a grate the combinationof supporting bars having sockets, each with a pair of parallel walls extending from the upper edge of each bar, the said socketsyconnected by curved bearings of greater diameter than the distance between said walls, dumping frames located between the supportingbars supported on said bearings, and movable filling blocks in said sockets vertically moved by the movements of the dumping frames.
